Module Eio_unix.ResourceSource

Eio resources backed by an OS file descriptor.

Sourcetype t = < fd : Fd.t >

Resources that have FDs are sub-types of t.

Sourceval fd : < t.. > -> Fd.t

fd t returns the FD being wrapped by a resource.

Sourcetype Eio.Generic.ty +=
  1. | FD : Fd.t Eio.Generic.ty
    (*

    Resources that wrap FDs can handle this in their probe method to expose the FD.

    *)
Sourceval fd_opt : Eio.Generic.t -> Fd.t option

fd_opt t returns the FD being wrapped by a generic resource, if any.

This just probes t using FD.
